Error: "https://zapier.com/api/platform/cli/check" returned "400" saying "App must validate against schema before running app checks"

[Laurent Pellegrino]

I am updating a Zapier CLI app. While running zapier build, I get the following error:

✔ Copying project to temp directory
✔ Installing project dependencies
✔ Applying entry point file
✔ Building app definition.json
✖ Validating project style › Error: "https://zapier.com/api/platform/cli/check" returned "400" saying "App must validate against schema before running app checks"

Note that npm run build passes with no problems.

Here is my .zapierapprc content:

{ "id": 3375, "key": "App1570" }

Using zapier build --debug or zapier validate --debug gives no more information.

I have no idea how to fix this. Any help?

Note that I already tried removing node_modules/, package-lock.json, and running again npm install. Always has the same error.

Here are the versions used:

$ zapier -v
* CLI version: 12.2.0
* Node.js version: v19.1.0
* OS info: linux-x64
* `zapier-platform-core` dependency: 12.2.0

Any update? Running into the same issue. It's unclear what is wrong.

Hello @lpellegr! Thanks for including all that debug info! The exception App must validate against schema before running app checks means that the specific CLI integration version is not passing our remote JSON Schema validation. What is the result of running zapier validate on your end? The output there should help pinpoint where the problem is.

As for npm run build working, that would depend on what you have defined as the custom build script in your CLI integration's package.json file. It may or may not be calling zapier build, which would be worth double checking.

If it helps, you can also optionally skip validation during the build step with the --skip-validation flag: zapier build --skip-validation. The --skip-validation flag is also available when using zapier push, although I would recommend not skipping validation when pushing unless strictly necessary.

Hi @rnegron . I am actually facing the same issue when running zapier validate. I am expecting that I would be able to see what the issue is if the schema validation throws any errors. But all I am getting is exactly the same as the title of the issue above.

I tried running zapier validate --debug but it does not give me any meaningful clues as to what is the root of the issue.
Here's the error that I am getting with the --debug flag passed in

I am getting the same response on zapier validate --debug unable to pinpoint the validation error. I am hoping someone follows up on this considering it was not solved

[Liam Innis]

I had the same error. In my case it was a typo in my outputFields.js, specifically an extra , at the end of the line from a find/replace. Not a generic solution by any means, but probably worth checking for similar for whoever sees this next.
